This invention generally relates to a pump and more particularly relates to a deep well pump especially adapted for use in4 deep water wells for providing water iiow for irrigation purposes and the pump may be employed wherever it is desired to pump liquid from a relatively deep well.

As is well know, well pumps have generally been classied as a shallow well type or a deep well type and the present inventionrrelates to a deep well type which employs a step-by-step pumping operation including an improved type of pump construction for providing a relatively large volume of water with all elements of the pump being removable from the casing for replacement, repair, cleaning or the like.

Another object of the present invention is to provide a deep well pump employing a centrifugal type of impeller which is associated with spiral deflector blades and an auger type or inclined blade type impeller in spaced relation thereto for electively converting the centrifugal force of the water to upward force of the water for pumping the water upwardly.

A further object of the present invention is to provide a deep well pump which may be provided with a number of pumping units as required for pumping the water from the well together with a centrifugal pump at the upper end of the well casing for providing water pressure for spraying the water in the event a spray type irrigation system is being employed.

Other objects of the present invention will reside in its simplicity of construction, ease of removing and replacing various elements, adaptations for its particular purposes and its relatively inexpensive manufacture and cost.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 6 is an exploded group perspective View illustrating the elements of one pumping unit.

Referring now specifically to the drawings, the numeral 10 generally designates the deep well pump of the present invention which is adapted to be inserted into well casings 12 disposed in the ground 14 for pumping water' lo from the bottom of the well to an accessible point above the ground level for use of the water. The casings 12 are generally standard in size and range generally from 8 to l2 inches in diameter. inasmuch as the well casing 12 is usually provided with anirregular inner surface, the deep well pumplt) of the present invention includes an elongated tubular casing 18 whichl may be sectional with the sections joined together by the usual ange-type connection 20 wherein the casing 1S is disposed concentrically within the well casing 12 wherein the casing 18 may be supported therein in any suitable manner on the casing 12 wherein such support is not specifically illustrated in the drawings since it forms no part of the present invention. It is also pointed out that in some instances, the deep well pump 10 of the present invention may be inserted directly into the well casing without resorting 'to the casing 18 if the pump unit of the present invention is so constructed that it will t the well casing l2.

Within the elongated casing 13 a plurality of pump units generally designated by the numeral 22 are disposed all of which are driven from a rotatable pump rod 24 which is sectional in construction and secured by connectors 26 which are internally threaded for engagement with the opposite externally threaded ends 27 of the pump rod sections 24.

Each of the pump units includes a bottom plate 28 having a concave upper surface 30 and an O-ring seal 32 disposed in a peripheral groove for engagement with the inner surface of the casing 18 thereby forming a seal in conjunction therewith. The center of the plate 28 is provided with an enlarged opening 34 and depending arms 36 are secured to the undersurface of the plate 28 with a central hub 38 being supported by the arms 36 wherein a bearing 40 is disposed in the central opening of the hub 38 for journaling the lower end of the pump rod 24 therein. The'lower end of each of the arms 36 is cylindrical and designated by the numeral 42 for receiving a pin 44 which slides therein. A compression coil spring 46 is disposed between the inner end of each pin 44 and the bottom of the cylindrical portion 42 for urging the pins 424 outwardly into frictional engagement with the inner surface of the casing 18 thereby supporting the plate 28 within the casing 18 in concentric relation thereto. A thrustollar 48 is provided on the rod 24 below the hub 38 for assuring proper orientation of the hub and plate 2S on the pump rod 24.

Secured `to the pump rod 24 immediately above the plate 28 is an impeller generally designated by the numeral 50 and including a central ycylindrical hub portion 52 having a setscrew 54 for rigidly mounting the impeller on the rod 24 for rotation therewith. The cylindrical hub 52 extends from one end to theother of the impeller 50 and includes an fupper cylindrical plate 56 and a lower plate 58 interconnected by a plurality of radial blades 60 which have substantially parallel inner and outer inwardly inclined edges 62 wherein the inner edges terminate at the edge of an opening 64 in the bottom plate 58 which is in alignment with the opening 34 in the bottom plate 28 for receiving water therefrom.

The area between the bottom end of the cylindrical hub 52 and the inner edges l62 of the blades 60 form sub stantially an annular conical shaped area for receiving water at the inner edges of the `blades 64 by rotation of vthe impeller 50 causing outward Vand upward movement of the -water due to the inclined relation of the bottom plate l58 and the inclined surface 66 on the bottom of the upper plate 56. It will be noted that the incline of the lower plate 58 forms substantially a convex lower end for the impeller which substantially rests against or adjacent to the concave surface of the bottom piate 28 so that water will be pumped by `centrifugal motion outwardly and upwardly of the impeller 50. it will be noted that the outer edges 62 of the blades 60 actually terminate in spaced relation to the inner surface oi the casing 18m Aorder to permit upward passage of water from the impeller past the upper circular plate S6.

Y A combination and deilector and bearing arrangement 68Yis provided above the impeller 60 and includes a een tral hub portion 70'having an enlarged central socket 72 for receiving the hub 52 of the impeller 50 therein. At the lower end of the hub 70 is a circular plate 74 which is substantially equal in size to the upper plate 56 of the impeller 50 and plate 54 is disposed closely adjacent to the upper plate 56 without actually Vbeing in contact therewith. Depending from the periphery of the plate 74 is a plurality of spiral deflector blades 76 which taper to lower pointed ends 78. The outer periphery or edge of the blades 76 substantially dene a cylinder and the inner edges ofthe blades 76 define a frustofconical shape which is substantially the same shape as the outer periphery of the impeller 50 wherein the blades 76 will actually be disposed between the outer edges 62 of the blades 60 of the impeller 50 and the inner surface of the casing 18 substantially as illustrated in Figure 4 wherein water moving radially and upwardly from the blade by the centrifugal force caused by the rotation of the water with the blade60 will Contact the upwardly inclined surface of the deliector blades 76 thereby giving an upward lift or upward movement of the water whereby apportion of the radial force of the water is converted to upward thrust Ifor moving the water upwardly in the casing 18.

The hub is provided with a central bearing Si) rotatably journalling the shaft 24 and the upper end of the'hub 70 is provided with three radially extending arms 82 forming a support spider wherein the arms 82 are in the form of open-ended hollow sleeves slidably receiving a pin 84 provided with a compression coil spring 86 between the inner end of the pin 84 and the bottom of the tubular arm 82 thereby urging the pins 8d outwardly into engagement with the inner surface of the casing 18. Y

A collar 88 is disposed above the hub 70 and is secured on'the rod 24 by a setserew 90 for taking the thrust or weight of the rod 24 and transmitting it to the hub 70 and casing 18. 'If desired, a thrust bearing may be disposed between the thr-ust collar 88 and the upper end of the hub 70.

Disposed above the collar 8S in spaced relation thereto 1s an auger-type impeller generally designated by the numeral 92 which includes a central hub 94 secured on the shaft 2.4 by a setserew 96 and a plurality of spiral blades 978 which Vcoact to form a screw-.type auger impeller. The blades 93 have the outer edges thereof conforming closely to the linner'periphery of the casing 18 wherein added 'lift is given to the water being discharged from the `deflector blades 78 thereby moving a relatively large vvolume of water upwardly within the casing.

As'previously stated, a plurality of the'pump units 22 may be'e'mployed with the pump units being disposed in spaced relation along the pump rod 24 wherein the rotatable elements include the impeller 50 and the impeller .92 with all'of the other elements being stationary 'whereva relatively high volume rate.

The upper end of the casing 18 is provided with an extension 10d which may be of the same or less cross sectional area wherein the extension 100 is provided with a pump casing 102 having a centrifugal pump impeller 104- therein together with an auger type impeller 106 disposed in the extension 100 wherein the impeller 106 is similar in action to the impeller 92. The pump hous- 102 is provided with a tangential discharge pipe for connection to an irrigation line wherein the pump impeller 104 together with the impeller 106 will effectively discharge water into the irrigation line at a considerable pressure for spraying the water from the irrigation line if deemed necessary.

The centrifugal impeller 104 may be of the conventional type and is provided with vertically elongated drive shaft 112 which has the upper endgozf .thepurnp rod 24 secured thereto. The drive shaft 1.12 is supported in thrust bearings 114 by a thrust collar 116 .disposed within support brackets 118. The stufling box `1720 is provided on the pump housing 102 and with suitable packing 122 eing disposed therein together with a packing gland 1 24 which is adjusted by a bolt and nut arrangement 126. The support brackets 118 areA connected Vto the thrust bearing assembly by bolts 128 which can be removed for removing the shaft 112 andthe entire pump rod 24 with the various pump units 22 attached thereto. VAn electric motor 130 provided with Va reduction gear 132 is supported on the brackets 118 `in 'position for driving the shaft 112. It will be understood Ythat any suitable power device may be employed for driving the shaft 112 and pump rod 24 `wherein the speed should be relatively constant for producing a constant high volume tlow of Water from the casing 18.
